A new harpacticoid copepod is described from the waters off Jeju Island, Korea. This species displays a unique set of characteristics including a rostrum that is clearly demarcated from the cephalosome, a setular (spinular) row on the rostrum, a well-developed frill along the posterior margins of each body segment except for the cephalosome, long and cylindrical caudal rami, four segmented female antennules, paired genital apertures in the female, the absence of sexual dimorphism in legs P1–P4, and highly reduced P5 and P6 in the male. This combination of characteristics allocates the specimen to the family Nannopodidae Por, 1986, but the new species belongs to none of the extant genera within the family. A new genus, Doolia, is proposed. Nannopus is suggested as a sister taxon of the new genus based on shared plesiomorphic characteristics in the maxilliped, legs P1–P4, and P5. Doolia gen. nov. is the eighth genus of Nannopodidae, and an amended key for the genus is provided herein.

Two New Species

The discovery of a new genus of Heatherellidae in New Zealand has led us to revise this enigmatic family and its constituent genera. Aheatherella n. gen., based on A. mira n. sp. from the North Island of New Zealand, lacks some of the derived character states that link the Australian Heatherella, most notably the lack of sexual dimorphism in the dorsal shields and in the presence of peritremes in adult Aheatherella. Heatherella osleri n. sp. is described from New South Wales, extending the distribution of this genus beyond Queensland. New collection records of H. callimaulos and a key to the genera and species of the family are provided. We propose that the Heatherellidae—previously placed in its own cohort outside the Gamasina—are best considered a superfamily of gamasine mites within the subcohort Epicriiae.

A New Species

Abstract Delavalia qingdaoensis, a new species of harpacticoid copepod of the family Miraciidae is described based on specimens sorted from sediment samples collected in Jiaozhou Bay, Qingdao, Shandong Peninsula, Yellow Sea, in May 2008. The new species is easily distinguished from its congeners by the combined characters of the antennulary segments, an apomorphic setal formula of the swimming legs, and the shape of P5 in both sexes. It is remarkably similar to D. bocqueti (Soyer, 1971) and D. latioperculata (Itô, 1981), but it differs from D. bocqueti by features of the caudal rami, antennule, antennary endopod, mandibular exopod, maxillipedal basis, and P5 endopodal lobe; from D. latioperculata by the caudal rami, the inner setae of P1-P4 enp-1, P2 enp-2, and P4 exp-3, and the shape of P5 in both sexes.

The Family

A new genus, Catapaguropsis, and new species, Catapaguropsis queenslandica, are described from off Queensland, northeastern Australia. The new genus is compared and contrasted to two other genera of the family Paguridae, Catapagurus and Pteropagurus, with which it shares certain common characters. The new species is notable for its exhibited sexual dimorphism.

Dental Ontogeny

An exceptionally well-preserved silicified bivalve from the Upper Permian of Texas is described and assigned to a new genus and species,Cassiavellia galtarae, placed in the family Bakevelliidae. The species represents one of the earliest and best characterized unequivocal occurrences of the multivincular ligament in the superfamily Pterioidea. The silicified material provides a wealth of information on the morphology of inadequately known Paleozoic pterioideans, including hitherto undescribed aspects of the larval shell, auricular sulcus, muscle scars, and dental ontogeny. The discovery of the condyle-fossa complex on the anteroventral shell margin, a feature previously undescibed in Bivalvia, raises the question of the homology and taxonomic significance of the problematic subumbonal ridge-like structures in Pterioidea. In life,C. galtaraewas probably an epifaunal right-pleurothetic bivalve, byssally attached to hard or raised flexible substrata. In addition toC. galtarae, another new species,C. nadkevnae, is placed inCassiavellia.

Frame Construction

Phragmactis grayaeSpencer andSwataria derstlerinew genus new species are early (Ordovician) asterozoans (Echinodermata) that comprise the Phragmactinidae. Asterozoans are complexly varied, but as is true for other echinoderms, ambulacral construction is critical to interpretation. Phragmactinids share plesiomorphic aspects of ambulacral form and articulation with basal somasteroids and stenuroids whereas the apomorphic ambulacral expressions of asteroids and ophiuroids are lacking. Phragmactinids, like asteroids and ophiuroids, have only one virgal-series ossicle associated with each ambulacral, unlike the multiple ossicles of somasteroids and stenuroids. Virgal morphology of phragmactinids is reminiscent of expressions in somasteroids and stenuroids. Aspects of phragmactinid mouth frame construction are apomorphic. Morphologies of other ossicular series are similarly varied, and as a result, the family cannot be easily fitted into a recently proposed class-level taxonomy of early asterozoans; it is left in open nomenclature. Phragmactinid morphology does not indicate behavior significantly different from that of other early asterozaons. Asterozoan diversity suggests an early period of rapid evolutionary radiation.
